Tech News for Your Bottom Line

As if space travel wasn't out there enough, tech entrepreneur Elon Musk wants to blow the minds of frequent travelers. The founder of SpaceX and Tesla Motors says he wants to create something called the Hyperloop, a super-fast way to travel. How fast? You could get from Los Angeles to San Francisco in about 30 minutes.

You can put away your calculators. We've done the math for you. That's approximately 12.5 miles per minute, or about 750 mph. It puts California's bullet train project to shame. That train travels between the two cities in just under three hours.

In the meantime, Business Insider thinks it may have an idea of what the Hyperloop could be. In 1972, the Rand Corporation released a paper that detailed a high-speed underground tube system that could transport people across the U.S. Perhaps there are some similarities between a vacuum-powered tube system and the railgun-air hockey table style system Musk is talking about.

No doubt, traveling at high speed would be a boon for frequent business travelers. Imagine being able to travel across the U.S. in a matter of minutes, not hours.

But is the Hyperloop actually feasible? For a project like this to have cross-country potential, it would conceivably have to jump a number of serious political and engineering hurdles. Not easy. And not inexpensive, either.

Fingers crossed Musk's plan isn't just a pipe dream.
